VERTICAL DIRECT-ACTING ENGINE.

SPECIFICATION forming part of Letters Patent No. 683,407, datedSeptember 24, 1901.

Application filed January 26,1901. Serial No. $4,859. (No model.)

To all whom it may concern:

Be it known that I, HERMAN A. JENsENIUs, a citizen of the United States,and a resident of Camden, New Jersey, have invented certain Improvementsin Vertical Direct-Acting Engines, of which the following is aspecification.

My invention relates to certain improvements in vertically-arrangeddirectacting pumping engines of the triple expansion type.

The object of my invention is to counterbalance the weight of theseveral pistons, so that the engine will act uniformly. This obj'ect Iattain in the following manner, reference being had to the accompanying,draw- I ings, in which- Figure 1 is a view in elevation of the steam endof a vertical triple-expansion pumpingengine, partly in section. Fig. 2is a front elevation of Fig.- 1, partly in section; and Fig. 3 is a Viewof a modification of my invention.

I have shown my invention applied to a triple expansion duplex pumpingengine. The two engines are identical, and in the following descriptionI will allude to only one of the engines.

It will be understood that my invention can be applied to other thanduplex engines and the engine may have one or more cylinders.

A A are the standards supporting the steam portion of a pumping-enginein the present instance.

B is the high-pressure cylinder.

C is the intermediate cylinder, and D is the low-pressure cylinder. Thecylinder D is mounted directly upon the standards A, and supported bythis cylinder is a standard A, supporting the cylinder C, on which ismounted the cylinder 13. By this construction I am enabled to gainaccess to each of the cylinders, and while I prefer to use thisconstruction it is not essential in carrying out my invention.

Each of the cylinders B, C, and D is jacketed. The steam enters thejacket of the cylinder B through the pipe is from the main steam-supplypipe E, and steam is exhausted from the jacket of the cylinder B throughthe pipe a into the jacket of the cylinder C. A reducing-valve e in thispipe controls the passage of steam therethrough and regulates thepressure of steam in the counterbalancingcylinder. A pipe 6 connects thejacket of the cylinder C with the jacket of the cylinder D, and thejacket of the cylinder D is connected by a pipe e to an automatic pump Eor trap, which carries oft all water of condensation.

b is the piston of the high-pressure cylinder B, c is the piston of theintermediate cylinder C, and d is the piston of the low-pressurecylinder D. These cylinders are connected by a rod F. Extending from apiston 01 is a plunger d, which enters a cylinder G, secured to theunder side of the cylinder D, and this cylinder communicates with thepipe 6 through the pipe a A piston-rod F extends from this plunger d tothe pump-plungers. The plunger (1 has suitable packing (1 and the areaof the plunger is figured according to the. diameters of the severalcylinders, so as to counterbalance the weight of the unbalanced movingparts of the engine, such as the pistons, rods, 8:0.

I find that I can obtain sufiicient pressure from the steam utilized inthe jackets of the several cylinders to counterbalance the pistons. I

I I I are the valves of the several. cylinders B, C, and D, and thesevalves are connected by rods to valve mechanism J, actuated by aprojection on the piston-rod F. It will be understood, however, thatthis valve mechanism does not form a part of my present invention.

It will be understood that while I have shown my invention as applied toa tripleexpansion vertical engine, either single or duplex, it may beused in connection with one or more cylinders vertically'arrangedwithout departing from my invention.

Fig. 3 is a view showing the counterbalancing-cylinder G directly underthe lowermost cylinder of the series, but supported in dependentlythereof, the piston of the lower most cylinder being connected to thepumprod by two piston=r0ds d d and the piston of theeounterbalancing-cylinder beingconnected to; the cross-head {It by a rod61 as clearly shown.

I claim as my inVentionl. The combination of a steam-engine havin g oneor more cylinders vertically arranged, said cylinders being jacketed,another cylinder having its interior connected by piping to the jacketsof the above-mentioned cylinders, a plunger in said other cylinderoperatively connected to the pistons of said cylinders, the steam fromsaid jackets acting on the plunger in said cylinder to counterbalancethe weight of the unbalanced moving portions of the engine,substantially as'd'escribed.

2. The combination in a triple-expansion engine having the cylindersvertically arranged, of the three cylinders, each cylinderbeingjacketed,pipes forming communication between the several jackets ofthe cylinders, a cylinder under the lowermost cylinder and connected bypiping to the jackets of the engine-cylinders, a plunger extending fromthe piston of the lowermost cylinder and working in the cylindercommunicating with the jackets said plunger being actuated by steam fromsaid jackets to counterbalance the weight of the unbalanced movingportions of the engine, substantially as described.

The combination in a triple-expansion engine having the cylindersvertically arranged, of the three cylinders, one mounted above another,each cylinder being jacketed, a steam-supply pipe, a pipe leading fromthe steam-supply pipe to the jacket of the highpressure cylinder, a pipecommunicating the jacket of the high-pressure cylinder with the jacketof the intermediate cylinder, a pipe forming communication between thejacket of the intermediate cylinder with the jacket of the low-pressurecylinder, a pipe leading fromthe jacket of the low-pressure cylinder andconnected to a suction-pump, a cylinder secured to the under side of thelow-pressure cylinder and connected to the pipe leading to the pump ortrap, a piston for each of the high, intermedate and low pressurecylinders, said pistons being connected together, a plunger connected tothe low pressure piston and working in the cylinder coupled to thejackets, and a rod coupling the said plunger to the pumping mechanism,substantially as described. V

at. The combination in a triple-expansion engine having the cylindersvertically arranged, of the three cylinders one mounted above another,-eachcylinder being jacketed, a steam -supply pipe, pipes connecting theseveral cylinders, a pipe leading to a pump or trap, a cylinder underthe lowermostcylinder of the series, a plunger in said cylinder forcounterbalancing the unbalanced moving parts of the engine, saidcylinder being connected to the jackets of the engine-cylinders, and areducing-valve for regulating the pressure of steam in thecounterbalancingcylinder, substantially as described.

5. The combination in a steam-engine, having oneor more cylindersvertically arranged, said cylinders being jacketed, acylinder connectedby piping to the jackets of the enginecylinders, and a plunger in saidcylinder coupled to the pump-rod and to one of theengine-pistons,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. V p
